units on standard metrics must not be changed.<br>
<br>
Metric units are selected by a practical approach taking EV community <br>
conventions into account.<br>
<br>
Coulomb count for vehicle batteries is normally measured in Ah, just as <br>
energy is measured in kWh and power in kW.<br>
<br>
I've never seen kC or Joules used in an EV context, but if you see a <br>
need for this, go ahead.<br>
